My project makes extensive use of the C# Async feature. Often I have to task.Wait() or
the equivilant for tasks that I need to complete before my test code resumes.

These tests succeed only intermittently. When they fail the stack trace looks like this:
*** Failures ***

Internal Error
System.Threading.ThreadAbortException: Thread was being aborted.
HResult: -2146233040

Timeout of 1000 expired

Any ideas how to remedy this?

Hi, thanks for posting!

From the description shown, it looks like NCrunch or Xunit is enforcing a timeout of 1000 on your tests. Because the tests are asynchronous and involve waiting between threads, it's possible that while your system is under load, the test takes longer than 1000ms to execute and is therefore aborted during the test run.

Are you making use of any attributes to specify this test timeout? If not, have a look at the default test timeout project-level NCrunch configuration setting to see if this has been set lower than it should be.
